Prerequisite

Etymology

The name MUST have the 'DO' prefix as this class is derived from ApplicationObject, and hence is classified as a distributed object. For the same reason the rest of its name must be in lower case. This class is a simplified version of the ComponentList class.

Synopsis

This class is a container that allows many SkyComponents to be grouped together and manipulated as a group. In this respect this class is identical to the ComponentList class. The user is encouraged to read the synopsis of that class for a general description of the capabilities of this class.

This class is differs from the ComponentList class in the following ways:

All components are indexed starting at one. This means the first component in this class is obtained by component(1) rather than component(0) in the ComponentList class.
Copies of the components, rather than references, are returned to the user. This means that this class needs a replace function whereas ComponentList does not.
Components that have been removed from the list are stored in a temporary place. In the ComponentList class once they are deleted they are gone.
This class is derived from ApplicationObject and follows the AIPS++ conventions for "distributed objects". Hence the fuunctions in this class can be made accessible from glish.
This class can generate simulated components and add them to the list.

There is a one-to-one correspondence between the functions in the glish componentlist object (see the AIPS++ User Reference manual) and functions in this class. This is make simplify the porting from glish to C++ of a glish script using the componentlist distributed object.

Example

These examples are coded in the tDOcomponentlist.h file.

Example 1:

In this example a ComponentList object is created and used to calculate the ...

Motivation

This class was written to make the componentlist classes usable from glish

Thrown Exceptions

AipsError - If an internal inconsistancy is detected, when compiled in debug mode only.

To Do

Nothing I hope. But I expect users will disagree.

Member Description

qimager()

"qimager" ctor

qimager(MeasurementSet &thems, Bool compress=False)

Construct an qimager tool from a MeasurementSet and a flag indicating whether compression of attached calibration data columns is required

qimager(const qimager &other)

qimager &operator=(const qimager &other)

~qimager()

Bool open(MeasurementSet &thems, Bool compress=False)

Close the current ms, and replace it with the supplied ms. Optionally compress the attached calibration data columns if they are created here.

Bool close()

Flush the ms to disk and detach from the ms file. All function calls after this will be a no-op.
